Udupa, You can also search for this author in Sci. N doped porous carbons (NPCs) with different N concentrations were fabricated. The electrolytic reduction of nitrobenzene in strongly acidic medium produces phenylhydroxylamine which rearranges to p-Aminophenol. The electrochemical reduction performance of NPCs was evaluated by reducing nitrobenzene (NB), and the effects of nitrogen concentration were discussed. Electrochem. • Without the addition of such carriers, complete reduction is not possible. John Wiley, Interscience, New York (1949). Electrochemical reduction process is a promising method for wastewater treatment, and its performance is determined by cathode material. C. L. Wilson and H. V. Udupa,J. Reinhold: New York (1950). Nitrogen doped carbon is a kind of favorable cathode material for electrochemical reduction, but deep understanding for the effect of nitrogen concentration and reduction pathway is still needed.

Your IP: 104.248.9.228 Galvanostatic polarization measurements on a copper cathode in presence of titanic sulfate and nitrobenzene are presented. Pergamon, Oxford (1964). Efficient electrochemical reduction of nitrobenzene by nitrogen doped porous carbon. The reduction of nitrobenzene by an electrolytic method is fairly simple and it does not require the complicated equipment needed in the vapour phase reduction method. Various conditions such as current density, depolarizer ratio, temperature and concentration of the hydrogen carrier have been studied.
